Your Child's Immunizations: Pneumococcal Vaccines (PCV, PPSV)

Article Translations: (Spanish)

What Are Pneumococcal Infections?

The pneumococcal conjugate vaccine (PCV13) and the pneumococcal polysaccharide vaccine (PPSV23) protect against pneumococcal infections, which are caused by bacteria.

The bacteria spread through person-to-person contact and can cause such serious infections as pneumonia, blood infections, and bacterial meningitis.

PCV13 protects against 13 types of pneumococcal bacteria (which cause the most common pneumococcal infections in kids). PPSV23 protects against 23 types. These vaccines not only prevent infections in children who are immunized, but also help stop the infections from spreading to others.

PCV and PPSV Immunization Schedules

PCV13 immunizations are given to all infants as a series of four injections:

  • the first at 2 months of age
  • then at 4 months, 6 months, and 12–15 months

Some kids older than age 2 also might need a shot of PCV13 if they have missed one or more shots, especially if they have a chronic health condition (such as heart or lung disease) or one weakens the immune system (like asplenia, HIV infection, etc.). A doctor can decide when and how often a child will need to receive PCV13.

PPSV23 immunizations are recommended as added protection against pneumococcal disease in kids 2–18 years old who have certain chronic health conditions, including heart, lung, or liver disease; diabetes; kidney failure; a weakened immune system (such as from cancer or HIV infection); or cochlear implants.

Why Are the PCV and PPSV Vaccines Recommended?

Children younger than 2 years old, adults over 65, and people with certain medical conditions are at high risk of developing serious pneumococcal infections. These vaccines are very effective at preventing severe disease, hospitalization, and even death.

Possible Risks of PCV and PPSV Vaccines

Kids may have redness, tenderness, or swelling where the shot was given. A child also might have a fever after getting the shot. There is a very small chance of an allergic reaction with any vaccine.

When to Delay or Avoid PCV and PPSV Immunization

These vaccines are not recommended if your child:

  • is currently sick, although simple colds or other minor illnesses should not prevent immunization
  • has had a severe allergic reaction to a previous dose of a pneumococcal vaccine or to the DTaP vaccine

Caring for Your Child After PCV and PPSV Immunization

These vaccines may cause mild fever and soreness or redness in the area where the shot was given. Check with your doctor to see if you can give either acetaminophen or ibuprofen for pain or fever and to find out the appropriate dose.

When Should I Call the Doctor?

  • Call if your child missed a dose in the series.
  • Call if a severe allergic reaction or high fever happens after immunization.
